To alii whom it may'concern:

Be it known that I, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Cupboard-Latches,of which the following is a speciication.

My invention relates to improvements in cupboard-latches andthe main object of my improvement is to inclose the tail end of the latch without increasing the length of the case.

In the accompanying drawings, Figure 1 is a front elevation of my latch. Fig. 2 is a rear elevation. Fig. 3 is a side elevation showing thele face-plate and beveled end'of the latchbo t. a: of Fig. 1. Fig. 5 is a sectional View on the line y y of Fig. 1. Fig. 6 is a side elevation of the rear plate of my latch.

The case A is formed of sheet metal, the face-plate 7 of which is provided with a hole for the beveled end of the latch-bolt to slide in. This hole is made to conform to the shape of the latch-bolt at the head end, which shape will be described in connection with the latchbolt.

Above and below the body or middle por? tion of the case A, I form the wings S, the 'edges of the metal forming said wings being turned at right angles to their plate portion, as at 9, in. order to elevate said plate portion a little from the back face of the latch. Said wings may have any ordinary screw-holes formed in them, but I prefer to swage the Vcountersink of the screw-holes in the form of integral eyelets 10, as shown best in Fig. 5.

The sides l1 of the latch-bolt at its beveled or head end l2 are inclined towardeach other as they extend fromfront to rear, as shown in Figs. 2 and 3, and the hole in the face-plate 7 is of a corresponding shape, whereby the said end 12 is supported within said faceplate against moving to the rear during the The entire inward stroke of the latch-bolt.

said latch-bolt on the inside of the case is providedwith an ordinary yoke 13 for the L 'cams 14 of the knob 15 to act upon in the ordinary manner and also with a central stem 16 to guide the rear end of the latch, and about which stem I place the spiral spring 157. The rear end of this stem extends to the rear about Fig. 4 is a sectional view on the lineA the same distance as the ends of the yoke and is thns shorter than the stein in ordinary cupboard-turns. I support this stem by means of a lug 18 on the partial rear plate 19, said lng, as shown best in Fig. 4, standing in a vposition some distance from the end plate 20 of the case, so that the stem may have room to make its'fnll stroke wit-hout perforating said end plate, thereby avoiding the projection of the stem from the case, which projection is lobjectionable in the ordinary cupboard-latch. AtA the same time the case is not materially longer than is necessary for the yoke and cams to operate in. The cams in acting on the yoke to draw in the latch-bolt move along close to the inner face of the case A and over the end of the lug 18, which lug must be short enough not to interfere with the operation of said cams; This partial rear .plate at its ends enters the recesses in the rear side of the wings, and I prefer to secure it in place by extending the eyelets 10 through holes in said plate and clenching them over the same, as best shown in Fig. 5; but the other parts of my invention would be the same if this rear plate were secured in place in some other way. The partial rear plate extends only over a portion of the rear side of the plate-that is to say, it does not extend in the rear of the head of the latch-bolt, so as to support that end. I am'enabled to use this partial rear plate by having the sides 11 of the latch-bolt inclined, as shown, while the stem end of the latch-bolt is supported by the lug on said partial rear plate, and thus I make a cheap latch in which the stern never projects through the end plate of the case, and the latch-case is substantially no longer than is necessary for the proper operavtion of the cams and yoke.'

specific construction herein disclosed may be\ made, and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and'described,

but desire the liberty to make' such changes ssl I am aware that a prior patent shows a cup IOO . the face-plate and supported by the said faceplate, and the partial rear plate having the perforated lug,` for supporting the stein of the latch-bolt and having its ends resting Within the recesses ofthe wings 8 and secured to the rear side of said wings inside of the edges 9, substantially as described.

2. In a cupboard1atch, the combination of the latch-bolt having the yoke and stem, with the box-like case, the partial rear plate having the lug 18 on the inside of the case for supporting the stem of the latch-bolt and with a clear space between the front end of said lug and the rearvside of the front plate of said case, and a cam mounted on the inside of the said front plate of the case adjacent to the lug and arranged to pass through the space between the front end of said lug and the rear side of the said front plate for acting on the yoke of the latch-bolt, substantially as described.

HENRY G. VOIGHT.
